If you know the word which is common then use Contains String (CS).

or use FIND press F1 on find.

Thanks

This code might help u but also check with the options of search,find statements


data:text1 type string value 'sales order document'.
data:text2 type string value 'purchase order document'.
data:mcount type i.

data:begin of it_text occurs 0,
        value type char255,
 end of it_text.




split text1 at space into table it_text.

loop at it_text.
  if text2 cs  it_text-value.
    mcount = mcount + 1.
  endif.
endloop.

write mcount.

Hi keshu,

Good try.

but here i am getting count as 0.

even i have count for order is 1 in text2 and count for document is 1.

my requirement is i have to count individuvally how many words are matching text1 in text2.

their individual count i have to print.

Thanks

Hi,

Try below code

TYPES : BEGIN OF ty_text,
          text(50) TYPE c,
         END OF ty_text.

DATA : str1 TYPE string,
       str2 TYPE string.

DATA : cnt TYPE i.

DATA : it_itab TYPE TABLE OF ty_text,
        wa_itab TYPE ty_text,
        it_itab1 TYPE TABLE OF ty_text,
         wa_itab1 TYPE ty_text.

str1 = 'sales order document hello go'.
str2 = 'purchase order document hello go'.

SPLIT str1 AT space INTO TABLE it_itab.
SPLIT str2 AT space INTO TABLE it_itab1.

LOOP AT it_itab INTO wa_itab.
  READ TABLE it_itab1 INTO wa_itab1 WITH KEY text = wa_itab-text.
  IF sy-subrc = 0.
    cnt = cnt + 1.
  ENDIF.
ENDLOOP.

cnt will have the matched no of word count

check this


data:text1 type string value 'sales order document'.
data:text2 type string value 'purchase order document'.
data:mcount type i.

data:begin of it_text occurs 0,
        value type char255,
 end of it_text.


data:begin of it_text2 occurs 0,
        value type char255,
 end of it_text2.




split text1 at space into table it_text.

split text2 at space into table it_text2.

loop at it_text.
  mcount = 0.
  loop at it_text2 where value = it_text-value.
    mcount = mcount + 1.
  endloop.
  skip 1.
  if mcount > 0.
    write: it_text-value,mcount.
   endif.
endloop.
